A series of improvisations, recorded around 1957, and featuring Pauline Oliveros, Loren Rush, Terry Riley, Laurel Johnson, Robert Erickson, and Bill Butler. The instrumentation for these five pieces is varied and unspecified, but seems to include piano, percussion, flute, and a trumpet, or some other brass instrument. The first improvisation is used as accompaniment for a lengthy monologue. These early experiments with aleatoric and improvisatory music serves as a valuable historical record chronicling the emergence of a new musical aesthetic that was to dominate contemporary classical music for much of the latter half of the 20th century, and hints at the type of minimal and chance compositions for which many of the performers would later become famous. As such they should be of great interest and provide considerable enjoyment to any fan or student of 20th century, avant-garde, classical music.
